根据 WooCommerce 订单商品产品标签更改 PayPal 电子邮件

Question

我正在努力寻找解决问题的方法。我想根据 WooCommerce 产品标签更改 PayPal 电子邮件。 示例：对于服装、鞋类和箱包标签，请发送电子邮件 emailpaypal1@domain.com ..... 如果标签是雪、阳光、花园，则将电子邮件发送到 paypal2@domain.com 等...

我在多次搜索后找到了这段代码，但我无法让它与标签一起使用。我都试过了，但都失败了:(。谁能给我修改后的标签代码？非常感谢！！

// 1. Switch PayPal email for Product ID
add_filter( 'woocommerce_paypal_args' , 'switch_paypal_email_based_product', 9999, 2 );
function switch_paypal_email_based_product( $paypal_args, $order ) {
 
    foreach ( $order->get_items() as $item_id => $item ) {

        // ENTER PRODUCT ID HERE
        if ( 123456 == $item->get_product_id() ) {
            // ENTER OTHER PAYPAL EMAIL HERE
            $paypal_args['business'] = 'another-paypal@example.com';
            break;
        }
    }
    return $paypal_args;
}
 
// 2. Avoid IPN Failure after switching PayPal email for Product ID
require_once WC()->plugin_path() . '/includes/gateways/paypal/includes/class-wc-gateway-paypal-ipn-handler.php';
 
class WC_Gateway_Paypal_IPN_Handler_Switch extends WC_Gateway_Paypal_IPN_Handler { 
    
    protected function validate_receiver_email( $order, $receiver_email ) {
 
        if ( strcasecmp( trim( $receiver_email ), trim( $this->receiver_email ) ) !== 0 ) {
 
            // ENTER HERE SAME PAYPAL EMAIL USED ABOVE
            if ( $receiver_email != 'another-paypal@example.com' ) {
 
                WC_Gateway_Paypal::log( "IPN Response is for another account: {$receiver_email}. Your email is {$this->receiver_email}" );
                $order->update_status( 'on-hold', sprintf( __( 'Validation error: PayPal IPN response from a different email address (%s).', 'woocommerce' ), $receiver_email ) );
                exit;
            }
        }
    }
}
 
new WC_Gateway_Paypal_IPN_Handler_Switch();

更新

我把它放在子主题的function.php 文件中，但它在我附加给你的那一行中给了我一个错误。我抄得不好？ :(。我是不是忘记了什么？非常感谢！！

Error: syntax error, unexpected 'array' (T_ARRAY), expecting ')' 

---

if ( ! in_array( $receiver_email array('paypal1@domain.com', 'paypal2@domain.com') ) {

他在这一行给我的错误......但老实说，我不知道 wordpress 的程序是否理解它是否在这一行中，或者你是否错了:(。它不会让我保存代码对于这个问题...

要处理订单商品上的特定产品标签，您可以通过这种方式使用 WordPress has_term() 函数，将您的第一个挂钩函数替换为以下内容：

add_filter( 'woocommerce_paypal_args' , 'switch_paypal_email_based_product_tags', 9999, 2 );
function switch_paypal_email_based_product_tags( $paypal_args, $order ) {
    // Here define your product tags
    $tag_terms1 = array('clothing', 'footwear', 'bags'); 
    $tag_terms2 = array('snow', 'sun', 'garden');

    // Here define your emails
    $email1     = 'paypal1@domain.com';
    $email2     = 'paypal2@domain.com';
 
    foreach ( $order->get_items() as $item_id => $item ) {
        if ( has_term( $tag_terms1, 'product_tag', $item->get_product_id() ) ) {
            $paypal_args['business'] = $email1;
            break;
        } elseif ( has_term( $tag_terms2, 'product_tag', $item->get_product_id() ) ) {
            $paypal_args['business'] = $email2;
            break;
        }
    }
    return $paypal_args;
}

// Avoid IPN Failure after switching PayPal email for order items product tags 
require_once WC()->plugin_path() . '/includes/gateways/paypal/includes/class-wc-gateway-paypal-ipn-handler.php';
 
class WC_Gateway_Paypal_IPN_Handler_Switch extends WC_Gateway_Paypal_IPN_Handler { 
    
    protected function validate_receiver_email( $order, $receiver_email ) {
 
        if ( strcasecmp( trim( $receiver_email ), trim( $this->receiver_email ) ) !== 0 ) {
 
            // Here set same paypal emails used above in the array
            if ( ! in_array( $receiver_email array('paypal1@domain.com', 'paypal2@domain.com') ) ) {
 
                WC_Gateway_Paypal::log( "IPN Response is for another account: {$receiver_email}. Your email is {$this->receiver_email}" );
                $order->update_status( 'on-hold', sprintf( __( 'Validation error: PayPal IPN response from a different email address (%s).', 'woocommerce' ), $receiver_email ) );
                exit;
            }
        }
    }
}
 
new WC_Gateway_Paypal_IPN_Handler_Switch();

代码进入活动子主题（或活动主题）的functions.php 文件中。它应该可以工作。

重要提示：这将无法正常工作，例如，如果您有一个来自 "clothing" 的订单商品和另一个来自 "garden" 的订单商品> 以相同的顺序。
